[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. First, fix the protective cover to the locking ring. The locking ring and the moving ring are fixedly connected. When the mixing tank is stirring, the mixing tank shakes violently. At this time, the protective cover will bounce slightly intermittently. This bounce will create a gap between the mixing tank and the protective cover. However, due to the tension of the straight spring, the moving plate moves downward, which causes the moving ring and the protective cover to move downward. The gap between the protective cover and the mixing tank disappears, preventing paint from splashing out.

[0015] 2. Place the protective cover onto the mixing tank and press it down so that the protective cover squeezes the air bladder inside the moving ring. The air bladder is under pressure and sends the internal gas through the connecting pipe to the locking ring. The gas inside the locking ring increases, and the increased gas pushes the locking block to move. The locking block moves into the locking groove of the protective cover, thus quickly fixing the protective cover.

[0016] 3. By rotating the shaft, the spur gear is driven to rotate. The spur gear drives the ring rack belt to rotate in a circle within the fixed ring. The scraper on the ring rack belt will remove the paint adhering to the protective cover, thus preventing the paint adhering to the protective cover from dripping onto the ground when the protective cover is removed, which would cause pollution to the external environment, and also reducing paint waste.
